Abstract
Abstract A covering device for a skylight in a flat roof including a frame mounted in the skylight opening and having horizontally disposed reflector panels that are inclined relative to the roof. The frame is rotatable and can be tilted or the panels can be tilted to follow the relative movement of the sun.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
A covering device for a skylight for use on substantially horizontal roofs of buildings, comprising a supporting frame mounted in the skylight, said frame having an upper surface disposed in a plane and a central axis of rotation perpendicular to the plane of said upper surface of the supporting frame; a plurality of individual, planar triple reflector panels parallely mounted in said frame, said panels being inclined with respect to the plane of the upper surface of the supporting frame; and means for rotating said frame about its said axis to follow the azimuth of the sun thereby confining the angle of incidence of the direct rays of the sunlight to within an approximate angle of + OR 22.5* with respect to a line perpendicular to the said planar reflector panels.
Claim 2
Dependent Claim
131 words
A covering device for a skylight for use on substantially horizontal roofs of buildings, comprising a supporting frame mounted in the skylight, said frame having an upper surface disposed in a plane and a central axis of rotation perpendicular to the plane of said upper surface of the supporting frame; a plurality of individual, planar triple reflector panels parallely mounted in said frame, said panels being inclined with respect to the plane of the upper surface of the supporting frame; and means for rotating said frame about its said axis to follow the azimuth of the sun thereby confining the angle of incidence of the direct rays of the sunlight to within an approximate angle of + OR 22.5* with respect to a line perpendicular to the said planar reflector panels.
Claim 3
Dependent Claim
19 words
A covering device according to claim 1 in which the supporting frame for the triple reflector panels is circular.
Claim 4
Dependent Claim
26 words
A covering device according to claim 1 in which the supporting frame is mounted on horizontal rollers and guided on its external periphery by perpendicular rollers.
Claim 5
Dependent Claim
26 words
A covering device according to claim 1 in which the supporting frame is connected with a driving motor for the rotational movement about the central axis.
Claim 6
Dependent Claim
16 words
A covering device according to claim 4 in which the driving motor is a stepping motor.
Claim 7
Dependent Claim
29 words
A covering device according to claim 1 in which the supporting frame is disposed in a space between a lower glass pane and a dome made of transparent material.
Claim 8
Dependent Claim
31 words
A covering device according to claim 1 in which the supporting frame is disposed in a space between a lower glass pane and a saddle-shaped roof construction made of transparent material.
Claim 9
Dependent Claim
18 words
A covering device according to claim 6, in which the lower glass pane is constructed with a diffuser.
Claim 10
Dependent Claim
18 words
A covering device according to claim 7 in which the lower glass pane is constructed with a diffuser.
Claim 11
Dependent Claim
24 words
A covering device according to claim 6 in which the space between the dome and the lower glass pane is sealed against moisture diffusion.
Claim 12
Dependent Claim
26 words
A covering device according to claim 7 in which the space between the saddle-shaped roof construction and the lower glass pane is sealed against moisture diffusion.
Claim 13
Dependent Claim
28 words
A covering device according to claim 1, wherein said central axis is disposed so as to be inclined with respect to the substantially horizontal position of the roof.
Claim 14
Dependent Claim
35 words
A covering device according to claim 1, wherein said supporting frame is disposed in said skylight in such a way as to be tiltably adjustable with respect to the substantially horizontal position of the roof.
